2.9x - How to import multiple obj files?
You actually don't need to use an add-on to import multiple .obj files. You can manually continuosly keep on importing them. If you have saved it in a folder and there are too many of them, you can press shift and select the last file you want to import. If there are any files in the middle you don't need, go to the file explorer and drag the all the unnecessary files to the bottom. Then press shift to the last file you want to import and press import. The files might be imported might be in the wrong order and you have to arrange them. Or, you could import them one-by-one. I know it is difficult if there are too many files, but is less CPU intensive while loading all the meshes. This should work without any problems.
